Application filedMarch 28,1927. Serial No. 172L834.

This invention relatesto headlamps suitable for motor vehicles and the like.

One object of the invention is to simplify the assembly of the various parts constitut ing the head lamp and to reduce the number thereof to a minimum and these of relatively simple or standard construction.

One feature of the invention consists .in the door rim forming not only a support for the door closure, but 'also cooperating with other parts for retaining the same in position and for retaining orsupporting the reflector within the casing. i

The full nature of the-invention will be understood from the accompanying draw ings and the following description and claim: Fig. 1 is a front view of the invention. Fig. 2 is a sectional .view taken along the line 22 of Fig. 1 and in the direction arrows. .7

In the drawings 10 indicates a casing suitably mounted which is provided with a flange or shoulder 11 adjacent the front edge 5 thereof. Anannular seat 12 constitutes a an enveloping portion 16 that extends rearwardly and is telescopically associated with the casing and particularly the annular seat 12. A curled or fflanged edge '17 is adapted to abut the shoulder 11 and limit rearward movement of the rim relative to the casing 10.

19 supporting a contact terminalplug receiving socket 20 adapted to receive'a light bulb 21. ,The outer end of the reflector includes a rearwardly extendingportion 22 forming the cushion ring 13'. The reflector includes e an outwardly extending peripheral flange 23 that constitutes a bearing seat for the rear end of the cushion ring 18. I i

In assembling the head lamp the reflector is positioned in the casing with, the light bulb 21 secured in its socket, Cushion ring 13 is positioned in the annular groove formed between the casing and the" reflector and the lens closure 14 is then mounted upon the of the casingiwith door-"irimk the 15i esent form of the invention the annularseat -12is 1 shown provided with a plurality of'socket depressions 24 each including an inclined face'25 although an annular-groove may be employed. The forward face thereof bears againstthe peripheral flange 23 of the reflec- .torand the other or rearward :fac'e thereof engages'an abutment or equivalent in the form of a rivet 26 which has an inclined face 27 receivableby the same. The More said in reality constitutes "a construction by which bead 17 rests on seat 12, and the rim 16, by a downward movement puts,apres'- sureon closure 14 at point 15 and also cushion 13 is compressed between rear side of 14 and front of reflector flange. This flange is forced rearwardly against socket deprescompressing the parts through pressure of rivet 26 at '27 on rearward inclined face 25 thereof and at 15. I Y r V Two rivets 26 are illustrated and'these are positioned in spaced relation and in place of a third rivet, a-threaded bolt 28 having 'a conical end 29 isiprovided. A check nut or look washer 3O cooperates therewith for lockingbolt28 in adjustedposition, it having threaded engagement with-the aperture in the door rim mounting the same. Un-

threading of bolt. 28 until it is removable from the depression 24 permits the door rim with the lens to be tilted upon the' other two rivets until it sufliciently clears the cas i'ngfto permit the two rivets to be released sions 24 or annular ring if employed; thus from'the adjacent depressions 24', whereupon theentire construction can be readily) disv assembled. The formation of depressions The reflector 18 includes a central aperture 24 as shown instead of as an annular groove havlng an inclined wall is'preferred since it prevents the closure from rotating. about.

The inventionclaimed is: In a head lamp having a reflector and a or may closure and including. a casing and'a'door rim no nrotatively connected together, the

combination of a locking connection there between comprising an annular seat on the casing telescoped bythe rim and telescopically receivingthe reflector, said; rim bearing on the reflector through the closure, a plurality of depressions in said seat extend: ing inwardly and engageable by the reflector for limiting inward movement thereof, and

inwardly extending members carried by said rim and radially receivable by and extending the rimeasing, closure andmefieetor together in clamped r elation, one Of Saldl members being relatively and radially movable with respect to the rim for independent movement toward and away from the adjacent" deipression for rim and closure connection an disvconnectaom i In witness whereofyl have hereunto afiixed into said depressions, said members and=saidg 1 rmyasignaiurer I depressions having a radially and inwardly EDWARD. o. vALBRIGHT; a
